6s battery - I'm confused

[AllGold]

It was previously so bad that it couldn't possibly have sucked any more. From a full charge, it could only go less than a hour--on low power mode--doing absolutely nothing before shutting down.

Now, all the sudden it's not as bad. It still kind of sucks but appears to be usable. I can take it off the charger and use it a little without it immediately dropping precipitously plus let it sit idle for a couple hours.

It must know it's both scheduled for battery replacement, and I have been looking at new phones. :wink:

It has been showing 95% battery health the whole time.

"Low Power Mode" ? I have to keep my 6s in that mode or it sucks itself dry in less than 2 hours. And mine claims to be at 91%. And I had Apple replace the battery last year when they had that $25 price going.

I will say that 'performance management protections' make the phone almost unusable, so I turn it off all the time.

What version of iOS are you guys running?

My 6s is on 13.1.3 still, and no problems with the power running out. Original battery.

13.4.1
Purchased it January 2016.
Battery swap in December 2018.

I use it a lot.

....so it's like when one hits puberty.....or goes off to college......confusion.....???

Currently running 13.4 but I had the problem with a previous iOS.

I think the battery was replaced about 18 months ago but I'm not sure on the exact timing. It was also that kind of bad before the replacement--maybe even a little worse. After the replacement it was fine until recently.

We had both of our 6s' batteries replaced by Apple right at the end of the $29 deal, so maybe Nov or Dec 2018. A year later they were noticeably bad and have just gotten worse. Mine shows 89% right now and only lasts half a day; I don't want to ask my wife to check her's--it will just irritate her!

I have seen cases where an iPhone would use battery so fast that it would heat up. Restarting iPhone did not help. A hard reboot (press home and power at the same time until iPhone reboots) fixed the issue in both cases.

I wonder if you did (intentionally or not) a hard reboot.

[AllGold]

I previously did a hard reboot intentionally and it had no effect on the problem.

Download Coconut Battery on a Mac. Plug your iPhone into the Mac and direct the app to your phone. It will give you a decent indication of the battery condition. I did this before taking my son's iPhone in. Coconut Battery's report was pretty close to the Apple proprietary software.
